CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser.No. 60/900,263, filed Feb. 8, 2007, and U.S. Provisional Application No.60/961,190, filed Jul. 17, 2007, both of which are incorporated hereinby reference in their entirety.

BACKGROUND

For the fiber to the home market and other fiber markets, bidirectionaland triple-bidirectional data transmission is often required, which inturn requires multiple elements to be packaged and aligned in anoptoelectronic module. Typical examples of such modules that includemultiple elements are a bidirectional module, also known as a diplexer,and triple bidirectional module, also known a triplexer.

A common approach to manufacturing both diplexers and triplexer modulesis to create a housing that is implemented as two or more pieces. Thetwo or more pieces are then fit together using known fabricationprocesses. Often, however, this multiple piece approach requires two ormore fabrication operations to achieve the necessary accuracy and/orfunction of all the features. Accordingly, the multiple piece approachis expensive and time consuming.

Accordingly, what would be useful in the art is to have a single piecediplexer and/or triplexer housing that easy to manufacture and is lowcost.

DETAILED DESCRIPTION

Reference will now be made to figures wherein like structures will beprovided with like reference designations. It is understood that thedrawings are diagrammatic and schematic representations of exemplaryembodiments of the invention, and are not limiting of the presentinvention nor are they necessarily drawn to scale. It is also understoodthat reference to a “first”, or a “second” etc. element (such as a firstand second receptacle) in this description and in the claims is meant todistinguish one element from another and is not meant to implysequential ordering unless explicitly stated.

Reference is first made to FIGS. 1A-1D, which illustrate different viewsof one embodiment of a one piece diplexer housing in accordance with theprinciples of the present invention, designated generally at 100. Notethat the embodiment of FIGS. 1A-1D is only one of numerous embodimentsin which the principles of the present invention may be practiced andshould not be used to limit the scope of the appended claims.

Diplexer 100 is implemented as a one piece housing, which may bemanufactured using Metal Injection Molding (MIM) processes as will bedescribed in further detail to follow. In some embodiments, diplexer 100may be made from metal. Examples of metals that may be used include, butare not limited to, carbon steel, and 416 steel. Other suitablematerials known in the art may also be used to make triplexer diplexer100. Since only one piece is used as a housing, additional requiredalignment and attachment steps of multiple piece housings are reduced toa minimum, resulting in higher reliability and lower assembly cost whencompared to multiple piece housings.

As shown in FIGS. 1A-1D, diplexer 100 includes a first receptacle 110that is configured to hold an optical device such as an opticaltransmitter assembly 150. As illustrated, first receptacle 110 has twostepped diameters. For example, a first portion 112 has a diameter D1.As is illustrated in FIG. 1D, diameter D1 is sized large enough toreceive a laser header 152.

Receptacle 110 also includes a second portion 114 that has a diameter D2that is typically smaller than diameter D1. As illustrated, the changeor step between the diameters of portions 112 and 114 creates a step 113inside of receptacle 110. As is illustrated in FIG. 1D, diameter D2 issized large enough to receive a laser can 154.

A third portion 116 of receptacle 110 has a diameter D3 that istypically smaller than diameter D2. As illustrated, the change or stepbetween the diameters of portions 114 and 116 creates a step 117 insideof receptacle 110. As is illustrated in FIG. 1D, diameter D3 is sizedlarge enough to receive an optical isolator 156, which may or may not bepart of laser assembly 150.

In like manner, diplexer 100 includes a second receptacle 120 that isconfigured to hold an optical assembly such as a photodiode assembly160. As illustrated, second receptacle 120 has two stepped diameters.For example, a first portion 122 has a diameter D6. As is illustrated inFIG. 1D, diameter D6 is sized large enough to receive a photodiodeheader 162.

Receptacle 120 also includes a second portion 124 that has a diameter D7that is typically smaller than diameter D6. As illustrated, the changeor step between the diameters of portions 122 and 124 creates a step 123inside of receptacle 120. As is illustrated in FIG. 1D, diameter D7 issized large enough to receive a nose portion of assembly 160.

A third portion 126 of receptacle 120 has a diameter D8 that istypically smaller than diameter D7. As illustrated, the change or stepbetween the diameters of portions 124 and 126 creates a step 125 insideof receptacle 120. As is illustrated in FIG. 1D, diameter D8 is sizedlarge enough to receive a photodiode lens 164.

Diplexer 100 also includes a third receptacle 130 that is configured toreceive an optical fiber such as fiber 170. Receptacle 130 has adiameter D5 that is sized large enough to receive the fiber.

As also illustrated, diplexer 100 further includes a pocket 140 forselective filter alignment. Pocket 140 has angled surfaces 142 and 144,with angled surface 142 being where the selective filter, such as filter190 of FIG. 1D, may be placed inside single piece diplexer 100. Angledsurface 142 allows for convenient positioning of filter 190 before it isattached permanently to the surface with epoxy, which results in fasterand more accurate attachment. Angled surfaces 142 and 144 are configuredto reduce cross talk and/or back reflection between optical signalsduring operation of diplexer 100. Note that pocket 140 is a throughpocket that allows an optical signal to be transmitted between anoptical assembly residing in first receptacle 110 and the fiber residingin third receptacle 130 and allows an optical signal to be transmittedbetween an optical assembly residing in second receptacle 120 and thefiber residing in third receptacle 130. Advantageously, pocket 140 is anintegral part of diplexer 100, thus removing the need for separate partsto house filter 190.

Referring now to FIG. 1D, a one piece diplexer 100 is shown fullypopulated with various optical assemblies, filters, and an opticalfiber. As previously described, transmit assembly 150 may be placed infirst receptacle 110, photodiode assembly 160 may be placed in secondreceptacle 120 and fiber 170 may be placed in third receptacle 130. Notethat the placement of the various components in a specific receptacle isfor illustration only and is not to be used to limit the scope of theappended claims. One of skill in the art will appreciate that thevarious components may be placed in other receptacles as circumstanceswarrant.

Returning now to FIG. 1A, it is shown that first receptacle 110 includescompliant press fit features 115.

As further shown, triplexer 200 includes a rectangular through hole 250,which advantageously may be manufactured using the MIM process.Rectangular through hole 250 allows an optical signal to be transmittedbetween optical assemblies residing in first, second and thirdreceptacles 210, 220, and 230 and a fiber residing in fourth receptacle240.

Placed inside of rectangular through hole 250 are angled surfaces 260,265, 266, and 267. Angled surfaces 260 and 265 are configured to holdselective filters 295 and 296 respectively. Angled surfaces 260 and 265allow for convenient positioning of filters 295 and 296 before they areattached permanently to the surface with epoxy, which results in fasterand more accurate attachment. Angled surfaces 260, 265, 266, and 267 aredesigned to reduce cross talk and/or back reflection between opticalsignals during operation of triplexer 200. Advantageously, rectangularthrough hole 250 and angled surfaces 260, 265, 266, and 267 are anintegral part of triplexer 200, thus removing the need for separateparts to house filters 295 and 296.

Referring now to FIG. 2D, a one piece triplexer 200 is shown fullypopulated with various optical assemblies, filters, and an opticalfiber. As previously described, transmit assembly 270 may be placed infirst receptacle 210, photodiode assembly 285 may be placed in secondreceptacle 220, photodiode assembly 280 may be placed in thirdreceptacle 230, and fiber 290 may be placed in fourth receptacle 240.Note that the placement of the various components in a specificreceptacle is for illustration only and is not to be used to limit thescope of the appended claims.

Theangled pocket receptacles 350 and 360 are triangular in shape in FIGS.3A-3E. It will be appreciated, however, that angled pocket receptacles350 and 360 may be various shapes and sizes as circumstances warrant.For example, in some embodiments angled pocket receptacles 350 and 360may be shapes other than triangles. It should also be noted that in someembodiments, angled pocket receptacles 350 and 360 are manufactured togo through the entire thickness of one piece triplexer 300.

Angled pocket receptacles 350 and 360 include angled surfaces 352, 354,356 and 362, 364, 366 respectively. Surfaces 352 and 362 are configuredto hold selective filters 395 and 398 respectively. Surfaces 354 and 364are configured hold blocking filters 397 and 399 respectively. Surfaces356 and 366 are configured to hold additional filters as circumstanceswarrant, such as a filter 396. As with the previous embodiments, angledsurfaces 352, 354, 356 and 362, 364, 366 allow for convenientpositioning of the various filters before they are attached permanentlyto the surface with epoxy, which results in faster and more accurateattachment. In some embodiments, a cover (not shown) may be placed overangled pockets 350 and 360.

Angled surfaces 352, 354, 356 and 362, 364, 366 are designed to reducecross talk and/or back reflection between optical signals duringoperation of triplexer 300. Advantageously, the angled surfaces 352,354, 356 and 362, 364, 366 are an integral part of one piece triplexer300, thus removing the need for separate parts to house the variousfilters.

Compliant press fit features 315 and 345 allow for an opticalassembly and/or fiber to be press fit or interference fit into firstreceptacle 315 and/or fourth receptacle 340. The use of compliant pressfit features 315 and 345 advantageously allow for triplexer 300 to bemanufactured as one piece using the inexpensive MIM process. Note thatalthough FIG. 3E only shows receptacles 310 and 340 as includingcompliant press fit features 315 and 345, the other receptacles may alsoinclude compliant press fit features 315 and 345 as circumstanceswarrant.

Referring again to FIGS. 3A-3E, it is shown that in some embodiments onepiece triplexer housing 300 also includes cuts 305 and 306. Cuts 305 and306 may be manufactured using various machining techniques known in theart and are integral to the triplexer housing. Although illustrated asbeing round, cuts 305 and 306 may be other shapes such as angled slotsas circumstances warrant. Advantageously, cuts 305 and 306 help toreduce cross talk between the optical assemblies of triplexer 300. Thisis illustrated further in FIG. 3D by the arrows in cut 305, which showhow cut 305 helps to suppress cross talk between optical assembly 370and optical assembly 380.

Reference is now made to FIGS. 4A and 4B, which illustrate an embodimentof a triplexer 400 that includes multiple angled pocket receptacles. Asis illustrated, this embodiment includes a first receptacle 410 that istypically configured to receive an optical assembly such as a laserheader. Triplexer 400 also includes second, third, fourth, and fifthreceptacles 420, 430, 440, and 450 that are typically configured toreceive optical assemblies such as photodiode headers. A sixthreceptacle 460 is configured to receive a fiber. Receptacles 410-460 aresimilar to like receptacles previously described and so need not bedescribed in further detail. Further, compliant press fit features maybe included as circumstances warrant as previously described.

As previously mentioned, triplexer 400 includes multiple angled pocketreceptacles 480, 485, 490, and 495. These angled pocket receptacles areconfigured to hold various filters as previously described in relationto angled pocket receptacles 350 and 360. The use of multiple angledpocket receptacles in a one piece triplexer housing is partially enabledby an optical design that implements a collimated (or slightlyconvergent) beam as described in commonly assigned, co-pending U.S.Provisional Application Ser. No. 60/889,912, filed Feb. 14, 2007, whichis incorporated herein by reference in its entirety. Conventionalmultiple piece triplexers implement a strong convergent beam that doesnot leave enough space for multiple angled pocket receptacles such asthose seen in FIGS. 4A-4B. It will be appreciated that even though FIGS.4A-4B show four angled pocket receptacles, this is for illustrationonly. The principles of the present invention allow for more than fourangled pocket receptacles to be implemented as circumstances warrant.
